James Wiburd become "Keeper of the Caves" in 1903 and quickly discovered five more caves within eighteen months: the River, Pool of Cerberus, Temple of Baal, Orient and Ribbon Caves. He remained Keeper until 1932, when he left following a bitter dispute over the development of the Ribbon Cave for tourism.
The Chifley Cave, originally known as the Left Imperial Cave but named for Prime Minister Ben Chifley in 1952, was the first of the caves to be lit with electric light, as early as 1880. In 1968, the Orient Cave became the first in the world to be cleaned, due to contamination from a nearby coal boiler. This was entering the cave via a new tunnel blasted 400 feet through to the Orient cave in the 1950s to allow easier access (entering at Bat End). Steam cleaning was found to be damaging to the crystal formations, due to the rapid expansion and contraction caused by the heat from the steam, and these days water from the caves' own underground rivers is used if cave cleaning becomes necessary
